IMPROVEMENT IN SPOOLS FOR WINDING WIRE.

Specification forming part of Letters Patent No. 216,836, dated June 24,1879; application filed september 16, 187s.

u To all whom et may concern:

Be it known that I, EDWARD M. GRANDAL, of Chicago, in the county of Cookand State of Illinois, have invented certain new and usefullmprovementsin Spools for Winding Wire 5 and I do hereby declare the following to bea full, clear, and exact description thereof, which will enable othersskilled in the art to which my invention appertains to make and use thesame, reference being had to tire accompanying drawings, which form pantof this specilication, and in which- Figure l represents an end yiew ofa spool embodying my invention, and Fig. 2 represents a longitudinalsection of the same.

Like letters of reference indicate like parts.

The object of my invent-ion is to provide` a strorfg, light, and cheapspool upon which to wind wire, commonly used in connection withreaping-machines for binding the gavels of Wheat or other grain, and sothat the wire may be readily transported and used; and my inventionconsists in the construction and combination of the several parts of thespool, as hereinafter described Vand claimed.

In the drawings, A represents the body or axle of the spool, whichconsists of a hollow cylinder made of some strong and light Inaterial,preferably of wood or paper. B are disks or flan ges, made preferably ofsheet-iron, which form the ends ofthe spool A, and are provided withannular openings at theV center thereof, and are also provided withcorrugations o, formed therein by suitable dies, forlthe purpose ofgiving rigidity and strength thereto. B

are auxiliary disks, also provided with annular openings at the centerthereof, and which are also cut or stamped preferably from sheetiron,and are made concave or dish-shaped, as shown, for thepurpose of bracingand giving additional strength to the `flanges or disks B.

The peripheries ofthe auxiliary disks B are provided with a series ofdepressions or notches,

e, which are coincident with the corrugations in disks B, therebypermitting the entire peripheries of the auxiliary disks B to bear axleA, and its ends are bent and impinged' against the disks B by anysuitable machinery, and in such a manner as to clamp or rivet lirmlytogether the several parts of the spool, as shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- Y vAn improved spool for winding wire,consisting of the hollow axle A and thimble C; in combination with theflanges B, provided with the corrugations a, and the auxiliary concavedflanges B', provided with the depressions c, substantially as specified.
